I put 275/70 18 KO3 Load Range E tires on my Overtrail. Referring to the load inflation tables from BFG, 34 psi was their recommendation which matches the door jam numbers. I felt the ride was pretty good but not as good as my 5th Gen 4Runner with King shocks. I pull a 5000 lb off-road camper and to handle sway I put on the adjustable ADS shocks. I used Slee in Golden, CO for the installation. Initially, the shocks felt a bit too stiff even at the softest setting. But they seemed to break-in after a while and now I am quite impressed with how supple they are. When I am not pulling the trailer, I set them to the softest setting. I had thought this would be too uncontrolled but I find myself now purposefully driving over rougher road surfaces (lots of that in Colorado Springs) because I love feeling how the suspension soaks it all up in a supple way. Very happy with these. The rear axle is more weighty than what it is in the 4Runner so over the roughest stuff the soft setting is probably too soft so I'll be trying out other settings at the rear to see what happens,.
